Celestial Unicorn #5

Jul 23, 2021

Each creature with lifelink dealing combat damage causes a separate life-gaining event. For example, if two creatures you control with lifelink deal combat damage at the same time, Ajani's Pridemate's ability will trigger twice. However, if a single creature you control with lifelink deals combat damage to multiple creatures, players, planeswalkers, and/or battles at the same time (perhaps because it has trample or was blocked by more than one creature), the ability will trigger only once.

If Celestial Unicorn is dealt lethal damage at the same time that you gain life, it won't receive a counter from its ability in time to save it.

If you gain an amount of life "for each" of something or "equal to the number" of something, that life is gained as one event and Celestial Unicorn's ability triggers only once.

In a Two-Headed Giant game, life gained by your teammate won't cause Celestial Unicorn's ability to trigger, even though it caused your team's life total to increase.

The ability of Celestial Unicorn triggers just once for each life-gaining event, whether it's 1 life from Dazzling Angel or 4 life from Apothecary Stomper.
